The genomic DNA variations of wild litchi(Litchi chinensis Sonn.var.euspontanea Hsue)were analyzed using random amplified polymorphic DNA(RAPD).Twenty arbitrary primers generated 165 RAPD bands with the size ranging from 200bp to 1500pb,among which 122 were polymorphic.The UPGMA cluster was conducted on the base of matrix of genetic distance.The results showed 60 samples were divided into 6 small classes and there were some genetic variations in the population.
